Phys.org / Cave finds reveal modern humans and Neanderthals may have shared long-term cultural continuity
Tens of thousands of years ago, Homo sapiens coexisted with Neanderthals, Homo neanderthalensis. Many of us living today carry a small amount of Neanderthal DNA, indicating that the two species may have shared much more than ...
Phys.org / Quantum gravity tests may mistake ordinary spacetime for superposition
Everything around us, from atoms and molecules to planets and galaxies, is governed by two extraordinarily successful theories of physics: quantum mechanics and gravity. Quantum mechanics explains the behavior of the microscopic ...
Phys.org / What makes a star a star? A strange 'in‑between' celestial object is testing astronomers' boundaries
A star called TOI-2155 lies around 1,350 light-years (839 trillion miles) from Earth. It is a little bigger, heavier and hotter than the sun, and it is not particularly interesting or unusual in itself.
Phys.org / Greenland meltwater adds to AMOC weakening, but updated model finds no tipping point in sight
The state of the Atlantic Meridional Overturning Circulation (AMOC) has been a hot topic among climate scientists in recent years. The AMOC is crucial for climate regulation because it pulls warm surface water from the tropics ...
Phys.org / Spontaneous current loops in a kagome metal point to hidden quantum order
Quantum materials, materials exhibiting physical behavior governed by the laws of quantum mechanics, have proved promising for the development of numerous advanced technologies, including quantum technologies, memory devices ...
Phys.org / Analog gravity advance offers new insights into Hawking radiation from black holes
Hawking radiation is a form of radiation emitted by black holes, as theoretically predicted by Stephen Hawking. It suggests that black holes do not merely swallow matter—as had previously been assumed—but also emit very faint ...
Phys.org / Quantum semiconductor design could expand search for dark matter
Dark matter accounts for 85% of the matter in the universe, but scientists still do not know what it is made of. A study, published in Physical Review Letters, by Rice University researchers proposes a detector design that ...
Phys.org / Early parenting shapes the brain and socio-sexual behavior, rodent study shows
Past psychology studies have consistently highlighted the importance of social bonds for survival, showing that enduring relationships are linked with a longer life expectancy, a more resilient immune system, better cardiovascular ...
Medical Xpress / HIV vaccine triggers broadly neutralizing antibodies in 44% of primates
A new HIV vaccine developed by La Jolla Institute for Immunology (LJI), Scripps Research scientists and IAVI has the potential to protect humans from developing HIV infection and AIDS. This HIV vaccine is the first to generate ...
Tech Xplore / New AI add-on helps developers automate everyday programming tasks
Developers are increasingly relying on large language models (LLMs) for everyday computing tasks such as fixing bugs, explaining code and automating text-processing tasks like filtering logs.
Phys.org / First synthetic protein motor moves along DNA in controlled, programmable steps
Researchers from UNSW Sydney have built the first artificial protein motor capable of taking controlled, directional steps along a DNA track. The protein, dubbed Tumbleweed, moves by alternating between three "feet" that ...
Science X / Some dark personality traits may help the body handle stress more easily, finds new study
Better immunity to stress is a superpower most of us would like to possess. Surprisingly, people with certain dark personality traits do have better protection against stress than most people.
